The Wall Berlin '90 (1990)

In anticipation of his upcoming performance of "The Wall" in Berlin, Germany, Roger Waters released a promotional-only sampler in the summer of 1990.

Along with previously released cuts from his solo albums "Radio K.A.O.S.," "The Pros and Cons of Hitch Hiking" and Pink Floyd's "The Final Cut," Waters offered a couple of rare tracks.

The six-song, 29-minute CD contains "When the Tigers Broke Free" from the 1982 film "Pink Floyd The Wall." Previously released as a single in July 1982, its inclusion here marked the song's first release on CD. Consumers would have to wait until the 2001 release of "Echoes: The Best of Pink Floyd" for the song's first commercial release on disc. The version on "The Wall Berlin '90" differs slightly from the "Echoes" version.

The sampler also contains a re-recording of Floyd's classic "Another Brick in the Wall Pt. 2" by Waters and his Bleeding Heart Band.

On the inside of the CD sleeve there's a letter to radio personnel giving some background about The Memorial Fund for Disaster Relief, the charity Waters' Berlin concert benefited. Waters concludes by asking radio stations to support the event by mentioning the concert whenever they play cuts from the sampler.

The 2-CD document of the July 21, 1990, Berlin concert was released as "The Wall Live in Berlin" on Sept. 11 of that year.
